Techniques for efficient execution of queries. A query plan generated for the query is optimized and rewritten as an enhanced query plan, which when executed, uses fewer CPU cycles and thus executes faster than the original query plan. The query for which the enhanced query plan is generated thus executes faster without compromising the results obtained or the data being queried. Optimization includes identifying a set of one or more fact scan operations in the original query plan and then, in the rewritten enhanced query plan, associating one or more dimension context predicate conditions with one or more of the set of fact scan operations. This reduces the overall cost of scanning and/or processing fact records in the enhanced query plan compared to the original query plan and makes the enhanced query plan execute faster than the original query plan.
The current document is directed to a query-as-a-service system ("QAAS system") that collects enormous volumes of data from network-connected entities, referred to as "Things" in the phrase "Internet of Things," persistently stores the collected data and provides a distributed-query-execution engine that allows remote clients to continuously execute queries against the collected data. In a described implementation, both the raw data and query results are persistently stored in the QAAS system, with the raw data stored for significantly longer periods of time. Query results generated by the query-processing engine are securely transmitted to QAAS remote clients for distribution to file systems, storage appliances, applications, and other data sinks within client systems.

DATA STORAGE SYSTEM AND METHOD FOR CALIBRATING SAME
Disclosed herein are aspects of optical tape technology. A segment (1210) on media (1110) includes tracks (1220) with length (1230). Segments (1210) may be separated by gaps/defects (1310).

Abrégé
A chip package is described. This chip package includes a stack of semiconductor dies or chips that are offset from each other, thereby defining a terrace with exposed pads. A high-bandwidth ramp component, which is positioned approximately parallel to the terrace, electrically couples to the exposed pads. For example, the ramp component may be electrically coupled to the semiconductor dies using: microsprings, an anisotropic film, and/or solder. Consequently, the electrical contacts may have a conductive, a capacitive or, in general, a complex impedance. Furthermore, the chips and/or the ramp component may be positioned relative to each other using a ball-and-pit alignment technique. By removing the need for costly and area-consuming through-silicon vias (TSVs) in the semiconductor dies, the chip package facilitates chips to be stacked in a manner that provides high bandwidth and low cost.
